Using a Gigabit Switch

[Tech Reprise]

I was thinking of purchasing a Switch for my home network. Can anyone tell me if the switch will work for me or not?

 

My network is like this:

ISP Modem/ONU from where it goes to a Wifi router where I input the IP settings for Internet. 

 

I want to install a switch in between so that I can pull out a ethernet cable when needed to my PC for troubleshooting usage as my Modem is in a hard to reach place. 

 

So will this work or is this money wastage?

Ok, let me see if I understand what you're trying to do. You have your modem that goes to your Wifi router, that's all pretty normal. What router is this? (Make/Model)

 

Common home grade routers sold today typically have a basic 4-port switch built in. If you wanted to expand upon that switch, you could purchase another one. I don't quite understand what you mean by "where I input the IP settings for the internet" there is nothing you typically need to input manually here, so that's something I'm just curious about.

 

It sounds like you're interested in putting a switch between the modem and your router? I can't quite understand why you would need to do that. If this is a residential internet service, you're typically only going to get one public IP for use that would be assigned to your router. Plugging in another device between the modem and the router isn't going to be able to function and given that that router is also acting as a firewall for your network, you wouldn't want a PC directly connected to the modem anyway as it would have no protection. 

 

 

Anyway, some details about the hardware you have and more about what you're trying to accomplish might help us clear this up for you.

If your ISP doesn’t use DHCP and uses something like… PPOE is it? You have to manually configure your router in this case. But, I agree, I have never had to do this either.

Sounds like this to me as well, and I can’t think of a reason why anyone would need this. 
 

Also, yes, no firewall = you’re going to have a bad time. Windows should never be exposed directly to the internet. 
 

OP, what problem/issue are you trying to solve here?

We do this our service we provide all the time but this is using business FiOS and the customers have more than one static IP. I don't really think that's what's going on here but yeah we don't really know.

A switch is really not suitable for this, as the modem will only function with one device at a time.

 

You may be able to find an ethernet extension cable if you need to extend the socket from the modem to somewhere you can swap the cable more easily.

 

But why not just unplug the cable at the router end and plug that into the PC?
